LAMP.

SPECIFICATION forming part of Letters Patent No. 275,230, dated April 3, 1883.

Application filed February 10,1883. (No model.)

'To alt whom t may concern:

such as will enable others skilled in the art to which it appertains to make and use the saine.

My invention relates to lamps, and more especially to that class of lamps known as bracket-lamps,7 and is more particularly intended for use on sewing-machines when it is desirable to throw a strong light upon the work and at the same time protect the eyes ofthe operator against the glare from the reflector; and with these ends in view my invention consists in certain details ot' construction and combination ot' elements, hereinafter fully and in detail described, and then specilically designated by the claims.

1n order that those skilled in the art to which my invention appertains may understand more fully how to make and use my improvement, l Will proceed to describe the same in detail, referring by letter to the accompanying drawings, forming part ot' this specification, in which- Figure 1 is a perspective view, showing the device applied 'to astandard or base; and Fig. 2, a central vertical section, showing the contour ot' the lamp.

Similar letters denote like parts in both tigures.

A is the body ot' the lamp, and projecting therefrom are bracket-arms B C, perforated, as-seen at a b, and having set-screws D E.

F is a parabolic reector, having therein oval openings Gr, and at the bottom a hooklike spindle, H, all for the purpose presently explained. V

The body A is so formed that there are two drip-gutters, c d, into which the overflow ot' oil may collect and be readily removed.

ln .assembling` the parts oiAIA my improved lamp, I place the reflector over the lampchimney in such a manner that the shank H will be inserted within the openinga in the bracket-arm B. A standard, I, with a spindle or shank yot' suitable length, is then adapted within the opening b in the bracket-armC. This standard is provided with screw-holes @,whereby it may be securely fastened to any Woodwork or the like. By means of the set-screw D the reiiector may be raised or lowered at the will of the operator, and the angle ot' re- Ilection accordingly elevated or depressed.

In the application of my improvement the standard l is screwed onto a sewing-machine table, out of the way of the operating. parts,

and the lamp connected with said standard,

as hereinbefore shown. The lamp is swung around until the rays of light are reflected in the desired direction, and the retlector raised or lowered until the rays strike the workplate of the machine. By means of the setscrew D the retlector may be fastened at the desired elevation. Ihe set-screw E secures the lamp las against any l'urther rotary or swinging movement after the direction of the rays is determined.

The lamp can be readily detached from a sewing-machine when not in use, as tbe standard is the only stationary' part ot' the device.

`What I claim as new, and desire to secure by Letters Patent, is

l. A lamp having projecting from its body, and forming an integral part thereof', pertorated bracket-arms provided with set-screws, whereby the reflector may be attached and the lamp secured to a standard, substantially as set forth.

2. rlhe refiector F, having spindle H, in combination with the perforated bracket-arm B, projecting from the body of the lamp and forming an integral part therewith, and having set-screw D, substantially as shown and described.

3. The standard I, in combination with the perforated bracket-arm C, projecting from the body of the lamp and forming an integral part therewith, and having set-screw E, substantially as set forth.

4. The lamp A, having projecting therefrom, and forming an integral part therewith, bracket-arms B C, with set-screws D E, respectively, in combination with the reflector F, having spindle H, and standard I, substantially as herein before set forth.

In testimony whereot'I aix my signature in presence of two witnesses.
